Green Anaconda

Deceivingly fast and unwittingly strong, some snakes can even swallow an entire human whole -- such as the African rock python and the infamous green anaconda (pictured). Luckily for us, these babies are non-venomous. Not much of a silver lining, I know.

Great White Shark

Great white sharks made celebrity status with the best selling novel Jaws by Peter Benchley and the subsequent blockbuster film by Steven Spielberg -- both of which depicted the great white shark as a "ferocious man eater."
But despite a few rare exceptions, it has been concluded that feeding is not a reason sharks attack humans; as stated on Howstuffworks.com, "Humans are not on the menu. In fact, humans don't provide enough high-fat meat for sharks, which need a lot of energy to power their large, muscular bodies"

Piranha

Another fearsome predator with an appetite for flesh and travels is packs is the grisly omnivorous piranha. In his 1914 book Through the Brazilian Wilderness, Teddy Roosevelt famously described South American guides showing him a pack of famished piranhas reducing a juicy cow to bones in less than 60 seconds. Talk about a gruesome death.

Tiger

Large cats, with their awesome mix of brutal strength, cunning dexterity, and awesome speed are some of the most prolific human killers in the animal kingdom -- the tiger being the worst offender. They're an arrogant bunch, with most attacks taking place in broad daylight.

Lion

Lions didn't become king of the jungle for nothing. Bolder and even more aggressive than tigers, these feline killers will come to your village and literally hunt you. Usually a last ditch resort when these fearsome man-eaters are truly starving, some -- like the notorious Tsavo lions -- will pretty much hunt humans whenever they feel like it. In your average year, lions will maim and kill about 700 people.

Chimpanzee

Trips to the zoo and numerous features showing trained "domesticated" chimpanzees have given swaths of people the wrong idea -- that chimps are cute, friendly, human loving creatures. Because as good as they are at mimicking our friendly demeanors, they're just as likely -- especially in the wild -- to exhibit the worst of human nature, partaking in such activities as rape, assault, murder and infanticide.
In Africa -- where their habitat is under attack from deforestation -- hungry chimps are notorious for stealing babies and small children for food. Not so friendly after all.

Brown Bear

Brown bears, on the other hand, despite their scary demeanor, are actually quite shy and cautious. They rarely attack humans unless threatened. In certain cases, because of disease or extreme hunger, they can become quite aggressive. Obviously, given their size and strength, these mini outbursts can be devastating if humans are involved. In conclusion, stay away at all costs.

Spotted Hyena

Actual hyena attacks are rare relative to their man-eating counterparts, but according to the SGDRN (Sociedade para a Gestão e Desenvolvimento da Reserva do Niassa Moçambique), attacks on humans are likely to be vastly underreported.

Congo_Tiger_Fish

Jeremy Wade, host of the Discovery Channel program "River Monsters," holds the congo tiger fish he captured for Season 2 of the show. Several species of fish are lumped under the same name, usually characterized by their protruding teeth and fierce predatory behavior.
